ABSTRACT
<p><b>OBJECTIVE</b>To determine quercetin and kaempferol in the plant of genus Dysosma that come from different species, different plant parts or different growing areas, which provide the basis of rational utilization of Dysosma plants.</p><p><b>METHOD</b>The analysis was performed on a Diamonsil C18 column (4.6 mm x 150 mm, 5 microm) eluted with the mobile phase of methanol-water containing 0.1% phosphoric acid (6040). The flow rate was 1 mL x min(-1), the detection wavelength was 360 nm; and the column temperature was set at 25 degrees C.</p><p><b>RESULT</b>The linear ranges of quercetin and kaempferol are 0.22-1.1 microg and 0.42-2.1 microg. The average recoveries of quercetin and kaempferol are 97.1% (RSD 1.4%) and 99.6% (RSD 2.4%); respectively.</p><p><b>CONCLUSION</b>The contents of flavones in different species of Dysosma are significantly different.</p>
